Taw qhia
Zoo:
2,4-Dichlorobenzoyl chloride yog cov xim tsis muaj xim rau daj daj daj nrog cov ntxhiab tsw. Nws tsis ruaj khov ntawm chav tsev kub thiab yooj yim hydrolyzed thiab decomposed, yog li nws yuav tsum tau muab cia rau hauv inert gas. Nws reacts nrog hydrocarbons, aromatic amines, thiab cawv los tsim cov amides thiab esters sib xws.
Siv:
2,4-Dichlorobenzoyl chloride yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis thiab muaj ntau yam kev siv hauv cov organic synthesis. Nws tuaj yeem siv rau hauv kev npaj ntawm ntau yam benzoyl chloride derivatives thiab lwm yam organic compounds.
Txoj kev:
2,4-Dichlorobenzoyl chloride tuaj yeem tau los ntawm chlorination ntawm p-nitrobenzoic acid lossis p-aminobenzoic acid. Cov txheej txheem tshwj xeeb yog ua rau p-nitrobenzoic acid lossis p-aminobenzoic acid nrog thionyl chloride kom tau txais cov khoom nruab nrab, thiab tom qab ntawd cov khoom nruab nrab yog ntxiv chlorinated kom tau txais 2,4-dichlorobenzoyl chloride.
Cov ntaub ntawv kev nyab xeeb:
2,4-Dichlorobenzoyl chloride yog cov organic compound uas ua rau khaus thiab corrosive. Yuav tsum ceev faj thaum siv thiab tuav, tsis txhob sib cuag nrog daim tawv nqaij, qhov muag, thiab ua pa. Cov cuab yeej tiv thaiv tsim nyog, xws li cov hnab looj tes kuaj, tsom iav, thiab cov khaub ncaws tiv thaiv, yuav tsum hnav thaum lub sijhawm ua haujlwm. Kev sib cuag nrog cov khoom siv hluav taws xob thiab cov tshuaj oxidizing yuav tsum zam kom tsis txhob muaj hluav taws kub los yog tawg. Thaum khaws cia thiab thauj, nws yuav tsum tau muab kaw thiab khaws cia kom deb ntawm qhov hluav taws kub thiab cua sov.
